97. vhost/virtio multi-paths loopback test plan

Benchmark vhost/virtio-user loopback test with 9 tx/rx paths. Includes split ring mergeable, non-mergeable, vector_rx, inorder mergeable, inorder non-mergeable, packed ring mergeable, packed ring non-mergeable, packed ring inorder mergeable, packed ring inorder non-mergeable path.

97.1. Test Case 1: loopback test with packed ring mergeable path

  1. Launch vhost by below command:

    rm -rf vhost-net*
    ./testpmd -n 4 -l 2-4  --no-pci \
    --file-prefix=vhost --vdev 'net_vhost0,iface=vhost-net,queues=1,client=0' -- -i --nb-cores=1 --txd=1024 --rxd=1024
    testpmd>set fwd mac
    
  2. Launch virtio-user by below command:

    ./testpmd -n 4 -l 5-6 \
    --no-pci --file-prefix=virtio \
    --vdev=net_virtio_user0,mac=00:01:02:03:04:05,path=./vhost-net,packed_vq=1,mrg_rxbuf=1,in_order=0 \
    -- -i --tx-offloads=0x0 --enable-hw-vlan-strip --rss-ip --nb-cores=1 --txd=1024 --rxd=1024
    >set fwd mac
    >start
    
  3. Send packets with vhost-testpmd,[frame_size] is the parameter changs in [64, 1518]:

    testpmd>set txpkts [frame_size]
    testpmd>start tx_first 32
